A TQ will work really well as long as it’s not warped. Not sure why it’s voodoo science to so many. Having an original air door tool helps, but isn’t a deal breaker. I thought somebody was making new main bodies a few years back too.
Did someone say THE NEW AND IMPROVED air door tool ?
How is that "new and improved"? (What are we not seeing?) I looks like the yellow version (you?) sold years ago that have the flat stock "T" instead of a dowel and had knurling on the body.
